Specification of Letters Patent.

Patented Feb. 14, 1911.

Application filed November 18, 1909. Serial No. 528,640,

To all whom it may concern:

Be it known that I, JOISEPH N. l 3. BoNn, a citizen of the UnitedStates, residlng 1n the city of New York, borough of Manhattan,

I machinery require thorough overhauling labor, and, in many instances,expert skill is and cleaning at certain intervals. According to thepresent practice, .the parts composing the motor or machine areseparated or taken apart for such purposes, an'opera-- tion whichinvolves conslderable t1m e and necessary for the the parts. j

proper ire-assemblage of The object of my invention is to obviate,

' in many cases, theforegoing objections, and

to this end I provide an apparatus adapted to be easily carried by aWorkman and capable of dispensing, under pressure, a clean-' ingfluid'which will reach or penetrate into the crevices of the machineormotor for the purpose of flushing out the dust, oil, dirt and othermatter which tends to clog up the working parts.

In a preferred embodiment of the invention, my apparatus comprises aclosed tank constituting a chamber for the storage of the cleansingfluid, a pipe or hose at the bottom part of said tankfa nozzle on saidpipe,

. a. faucet or like device for controlling the flow of fluid throughsaid pipe, an air com- I pressor-or pump, and a pipe leading fromsaidcompressor or pump to the tank above the fluidlevel therein.

The invention will be hereinafter described more fully in connectionwith the accompanying drawings.

In the accompanying drawings I have illustrated one practical embodimentof the invention, but the construction shown therein is to be understoodas illustrative, only, and not as defining the limits of the invention.

Figure 1 is a vertical longitudinal section,

partly in e1evatio-n,'of a dispensing apparatus embodying my invention.-Fig. 2 we cross section, partly in plan, the plane of the sectionbeingindicated by the dotted line 2-2 of Fig. 1. Fig. 8 is a horizontalsect ion on" the line 33 of Fig. 1.

relation to the tank, the handle, may be A designates a tank which maybe composed of sheet metal or any other suitable material. Said tankisprovided with a sub stantially. closed chamber, a, wherein a cleaningliquid of any desired character may be deposited. The upper head, a, oftank, A, 1s provided with a filling orifice, b, which is normally closedby a cap, B, whereby the cap may be-removed so that the cleaning liquidmay be poured into chamber, a, up'to any desired level therein.

Attached to the bottom part of tank, A, is a cook or faucet, C, andconnected to this faucet 1s a pipe or hose, D. Said pipe is, preferably,in the form of a flexible tube, and at the free end of the tube is anozzle, (Z of any suitable construction.

In connection with the tank I employ an a rcompressor or pump, thecylinder,.e, of

which is positioned substantially cent-rally within tank, A. The lowerpart of the cy1- inder 1s fastened to a foot piece, a, by a liquid andair tight joint so that cylinder, 6, W111 not communicate with chamber,a, of the tank, whereby the liquid in the tank is precluded from flowinginto the pump cylinder. Within the pump cylinder operates a piston,

'E, which may be of any suitable or preferred COIlSlSIlIClJlOIl, andattached to said piston is a rod, E, the latter extending upwardly abovethe head, a, of the tank. The pump cylinder is substantially closed atits upper partbya cap, f, the .latter being, preferably, screwed upon aprojecting part of cylinder, e, and said cap, f, is provided with anaper ture, f, through which freely passes the piston rod, whereby thepiston may be reciprocated, and air is free to flow through theaperture, f, into the pump cylinder. Suitable means are provided for theoperation of v i the piston by hand,and in Fig. 1, the piston rodisshownashaving a handle, F, said handle being provided with a collar,g, the latter being attached to piston rod, E. The collar, 9, isprovidedwith a lockingplate, Gr, shown in Fig. 2, and opening through one edgeof this plate is a notch, g, in which is adapted to fit a headed lockingstud, 9 said stud being attached fixedly to the head or cap, f, of thepump cylinder. The handle, F, and rod, E, may be rotated by hand as wellas moved endwise, andshould it be desired to lock the handle and pistonin fixed turned in order to engage the notched plate, G, with headedstud, 9 whereby the entire apparatus may be easily carried by thehandle, F. In order to reciprocate the' piston, however, handle, F, andplate, G, must be turned in ordercto disengage the notched platefrom'the headed stud, and' at this time the handle may be operated forthe purpose of reciprocating the piston rod and the piston. 4

Foot plate, 6, is provided with an air passage, h, one end of said airpassage opening upwardly so as to communicate with the lower part ofpiston cylinder, 6. other end of theair passage opens'into a check valvechamber, h, which is providedin foot plate, 6', and communicating withthis check valve chamber is (the lower bent part, i,"of an air tube,"I.A check valve, H, preferably of the ball variety, is fitted loosely: inchamber, h, so as to open in one direction when air is compressed byadown- -ward movement of piston, E,thus permit-- ting the air to flowthrough the piston cylinder into and through tube, I.

;The--,air tube is positioned, preferably, within chamber, a, 'of the.tank and it lies adjacent and parallel: .to piston cylinder, 6. Theupperpart of the air tube is held firmly in position by suitable means,such as the 'brace, 71', and at its upper extremity the air tube isprovided with a valve seat, This- .upper part of theairtube communicateswith chamber, a, of the tank above the liquid level therein, and the aircompressed 'in pump cylinder, 6, is-free to flow from the pump; cylinderthrough the foot plate, and. through tube, I, into the upper part of.

- chamber a..

J designates a needle valve, the lower tapering, end of which isadaptedto operate in the orifice provided in thevalve seat,

at the upper extremity of tube, 1. The

j, for conveniently operating the same.

- Should it be found that the check valve, H,

- 'leaks, the needle valve, J, "may beoperated to tightly'close the exitat the upperen'd bf tube, I, thus precluding the air stored un-- derpressure in the upper part of chamber, a, from leaking through tube, I,and into the pumpcylin'der; In lieu of employing aball and a 'suitablecleaning fluid is poured through" opening, I into chamber, a, of thetank, after which cap, B, is. replaced. Faucet, C, being closed, thepump 'or compressor is operated by hand for the purpose of establishingair pressure upon theliquid con- The F, is turned in a-direction torelease notched plate, G, from headed stud, g and said handle is thenoperated to reciprocate rod,

E,'and piston, E. The air below said piston is compressed and forcedthrough passage, h, and tube, I, the air escaping from s the upper partof the tube into chamber, a.

The piston is operated a proper number of times to establish therequired pressure of air upon the cleaning liquid in the tank, and afterthis-operation the handle, F, may be turned in order to engage notchedplate, G,

with stud, 9 for the purpose of locking the. handle and the pistoninfixed relation to the tank. The apparatus may be carried by the handle,F, or it may be placed beneath the arm of the operator. In usingtheapparatus, faucet, C, is opened, and the liquid is expelled fromchamber, a, by air pressure sons to flow through tube, D, and nozzle, d.The cleansing liquid is ejected under pressure through the nozzle, andit will find its Way into the cracks, crevices and other inaccessibleplaces .of a motor and variousother kinds of machinery which it isdesired to clean. The cleaning liquid will flow out of the motor orother machine, and carry with it the dust, oil,- greas'e, dirt andother.

impurities which tend toclog the working parts of the machine andinterfere with its working operation. I

The employment of a check valve, such as H or K, precludes the air underpressure in chamber, a, from flowing throu h pipe, I,

assage, h, andpiston cylinder, e, but should 1t :happen that the checkValve H, is defective, valve, J, is operated to tightly closethe'opening in the upper part of tube, I,

whereby air under pressure in chamber,- a,

is precluded fromescaping through tubes, I,

and e. needle valveoperates in a suitable stufiing box, 7', attached tohead, a, of the tank, and said valve is provided with a thumb wheel,

Any. suitable cleaning, liquid may be employed, such as kerosene, andthis cleaning liquid may be easily introduced when cap, B, is removed.Under some circumstances I may omit the use-of-a cleaning liquid anddispense air from the chamber, a, the air 'beingifforced under pressureinto the tank by the operation of the pump, the air being retainedunderpressure in said chamber, a.

When using the apparatus for cleaning purposes with air as the cleaningagent, valve,

the upper art of'tube, I," was to preclude the air un er pressure inchamber, a, from escaping through'the tube, I, and passage, h, into thepiston cylinder, and then it is J, is adjusted to tightly close theopening in only necessary toopen the faucet, O, and

direct the current of airin tp theplaces to be cleaned by moving thenozzle, d, as required;
